TestDrive

Mike Conley has built a little script to... "fetch a review request [from ReviewBoard], grab the latest diff (yes, found an easy way past the lack of API there), check out a fresh copy of MarkUs, throw down the diff, set it up with some Sqlite3 databases, run your tests, and voila – go to localhost:3000, and you're running the review request diff." It's already helped him catch bugs that "just" reading code would have missed. Sweet.
